To all 'whom z'may concern:

Be it' known that I, JOHN R. DoNNELLY, a citizen of the United Statesq residing at Portland, county of Cumberland, State of Maine, have invented certain new and uses ful Improvements in Valves for Hydrocarbons, of uhic-h the following is a specification. v

This invention relates to valves and particularly toA valves forhydrocarbons.v I

In the burning of hydrocarbons the handling of ther fuel, either as a liquider as a vapor, involves considerable diiculty, owing to the presence of particles of unreduced or foreign matter in the fuel. especially true inV the'handling of hydrocarbon to be burned in self vaporizing torches or burners in which ythe liquid fuelis fed from a tank under an air pressure. In this practice there is a constant tendency to clog at various points in the system and particularly at the controlling valve which is depended upon to regulate the supplyof fuel to the torchor burner. It is particularly necessary in these self vaporizing torches to have them run uniformly and to avoid as far as possible any interruptions in the feed, as any inequalities in temperature or interruptions in the combustion affect the vaporization and are liable to produce carbonization and clogging in the burner and its discharge nozzles.

It is the object of the present invention to provide a\ valve capable of manipulation to overcome the clogging tendencies which have been heretofore so annoying. To this end Ihave provided a valve capable of adjustment to ne degrees of feed and havlng the possibilities of manipulation for the facile and prompt overcoming of clogging when the same occurs.

The structure and operation of my valve will'bemore fully described in the specicat-ion which follows. In this specification I' have described a particular embodiment of my invention as illustrative thereof, the same being shown in the drawings.

Like numerals of reference are employed throughoutspeciication and drawings to indicate corresponding parts and 1n "the drawings, Figure 1 isnan end view `of my Specification of Letters Patent.

aboutthe upper portion of the openingli to fit which the conical end of a valve stem Whe 1 0 for its operation, the same being threaded into a neck' 6 uponwhich a gland cap 9 is turned to suitably compress the packing. The valve Stem 8 is hollow and contains a secondary stem 12'threaded' at 14.- vfor engagement with the upper end of the valve stem 8 and controlled by a milled head 13. A gland cap l1 is screwedronsto the upper end of the stem 8 to compress a packing about the upper end of the stem 12. The lower end of this auxiliary stem 12 is reduced at 15 and at the lower end of the 48 is ground. The stem8 is provided with aI reduced portion 15 a conical shoulder 16 is formed below which the stem is still further reduced until it finally terminates .in a

needle 19. The lower portion of the bore of the stem 8 is formed with a seat 17 against which the conical shoulder of the auxiliary valve stem 12 bears. A minute passage indicated at 21 is formed in the .conical valve on the end of the stem r8. Lateral openings 18 are drilled through the stem 8 to complete the passage way through the stem. When the auxiliary valve 16 is screwed down on its seat 17 the needle point 19 projects slightly through the opening 21.

In operation my valve is employed as follows: Supposing that the supply pipe from the tank be screwed on at 2 and the deliveryA pipe to the burner be coupled at 3, with the valves set as shown in Fig. -3 the su ply is cut off. If it be desired to run the Iburner under ordinary conditions fuel is admitted from the opening 21 to the stem 8 and delivered through the openings 18 to the su ply pipe. These minute openings, are sufgcient to maintain the supply under ordinary conditions. If it be necessary, however, to suddenly increase the supply as in starting, the main valve stem may be backed up by turnin the hand wheel 10. With the valve set in t le position as shown in Fig. 2 for ordinary running, if a particle of sediment becomes lodged on the point of 'the stem 8 the auxiliary stem of the valve may be run down quickly by turning the milled,

head 13 until the needle 19 thrusts the clot from the opening 21. This may be donev quickly and frequentl sulces to clear the clot from the pomt. f, however, the clogging persists thevneedle 19 is projected as stated above and the valve stem raised slightly on its seat. The inrush of fuel will then clear the conical point of the stem 8 of the clot and the stem 8 may be returned and the auxiliary stem 12 again raised to return the valve to its normal position in which the fuel passes through the passages 21 and 18. It will thus be seen that the valve may be quickly mani ulated to overcome any clogging and the urners may be Amaintained under a constant feed which will maintain a constant heat.

Various modifications may of course be made in the construction and operation of Amydevice without departing from the spirit' valve on its end adapte and adapte of my invention if within the limits of the appended claim. y

What I therefore claim and desire to secure by Letters Patent is A valve of the class described com rising a casing, said casing havingY an inta e and outlet opening, a v partition dividing said casing between said openings, and having a passage way therethrough, a valve seat formed about said passage way, a hollow valve stem in said casin having a conical to nd said seat, a longitudinal openin through the conical point of said valve an communicating with said hollow stem, transverse openings in said valve stem communicating with one side of said casing, an auxiliary valve stem threaded lwithin said rst named valve stem, and a needle on the end of said auxiliary valve stem adapted to enter the opening in the (point of said first named valve to be protruded therethrough. In testimony whereof I alix my signature lin presence of two witnesses.
